What is sunscreen?
Sunscreen is a vital tool in protecting our skin from the harmful effects of the sun's ultraviolet (UV) rays. It is a lotion, spray, gel, or other topical product that helps to shield the skin from both UVA and UVB radiation. Sunscreen works by either absorbing the UV rays or reflecting them away from the skin, thus reducing the risk of sunburn, premature aging, and skin cancer. It is recommended to use sunscreen every day, even on cloudy or overcast days, as UV rays can still penetrate through the clouds. Additionally, sunscreen should be reapplied every 2 hours, especially after swimming, sweating, or toweling off. It is an essential part of any skincare routine and crucial for maintaining healthy, radiant skin.
Difference between chemical vs mineral sunscreen
Chemical sunscreens contain ingredients such as oxybenzone, avobenzone, octisalate, and octocrylene, which absorb UV rays and convert them into heat before they can damage the skin. On the other hand, mineral sunscreens use natural minerals like zinc oxide and titanium dioxide to create a physical barrier that reflects and scatters UV rays away from the skin.
One key difference between the two is their ingredient lists, with chemical sunscreens often containing more synthetic compounds compared to mineral sunscreens. Another difference lies in how they protect the skin, with chemical sunscreens absorbing UV rays and mineral sunscreens creating a physical barrier against them.
Potential health risks associated with chemical sunscreens include hormone disruption and allergic reactions to the synthetic compounds. On the other hand, natural minerals used in mineral sunscreens, while generally considered safe, may pose an inhalation risk in their nanoparticle form. Furthermore, some natural minerals may have environmental concerns when washed off into water bodies.
In conclusion, both types of sunscreen have their own set of pros and cons, and it's important to consider the ingredient lists and potential health risks when choosing the right sunscreen for your skin.
Chemical Sunscreen acts as a protective barrier by absorbing the sun's UV rays and preventing them from penetrating the skin. It's a popular choice for many because of its lightweight and non-greasy feel. However, there are specific considerations and guidelines to keep in mind when using chemical sunscreen to ensure its effectiveness and safety. Understanding how chemical sunscreen works and its potential impact on the skin and environment is essential for making informed decisions about sun protection.
Active Ingredients in Chemical Sunscreens
Chemical sunscreens commonly contain active ingredients such as oxybenzone, avobenzone, octisalate, octocrylene, and homosalate. These ingredients work by being absorbed into the skin and preventing damage from the sun through a chemical reaction.
When applied to the skin, these active ingredients become absorbed and form a thin, protective layer that absorbs and neutralizes UV rays. Oxybenzone and avobenzone absorb UVA rays, while octisalate, octocrylene, and homosalate absorb UVB rays. This absorption and neutralization process helps to prevent UV radiation from penetrating the skin and causing damage, such as sunburn and premature aging.
It is important to apply a broad-spectrum chemical sunscreen about 20 minutes before sun protection is required to allow the active ingredients to fully absorb and provide effective protection. Broad spectrum sunscreens offer protection against both UVA and UVB rays, ensuring comprehensive protection against sun damage.
In conclusion, the active ingredients in chemical sunscreens are crucial for protecting the skin from the harmful effects of the sun's rays, and applying a broad-spectrum sunscreen in a timely manner is essential for effective sun protection.

SPF stands for Sun Protection Factor. SPF number tells you how long the sun's UVB rays would take to redden your skin if you applied the sunscreen exactly as directed compared with the amount of time without sunscreen. If you used an SPF 30 product properly, it would take 30 times longer for you to burn than if you used no sunscreen. But what about those UVA rays we mentioned earlier? Unfortunately, many sunscreens do not protect against UVA rays. (Remember: these are the rays that can penetrate deep into your and your baby's skin!)To guarantee protection against UVA and UVB rays — both of which can cause cancer — choose a sunscreen with a “Broad Spectrum” label. This is the best way to protect your baby's skin!
